Abstract

A substrate for emitting a volatile material, the substrate comprising a first woven layer, a second woven layer, and a third layer. The first woven layer has a first weave pattern. The second woven layer has a second weave pattern that is different than the first weave pattern. The third layer is disposed between the first woven layer and the second woven layer. Further, the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

First claim

We claim:

1. A substrate for emitting a volatile material, the substrate comprising:
a first woven layer having a first weave pattern;
a second woven layer having a second weave pattern that is different than the first weave pattern; and
a third layer that is disposed between the first woven layer and the second woven layer,
wherein the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

2. The substrate of claim 1 , wherein the volatile material includes an active agent that is applied to at least one of the first woven layer, the second woven layer, and the third layer.

3. The substrate of claim 1 , wherein the first weave pattern is a first honeycomb weave pattern and the second weave pattern is a second honeycomb weave pattern.

4. The substrate of claim 1 , wherein the first weave pattern includes a first weave density, the first weave density being characterized by a first plurality of fibers of the first woven layer, and
wherein the second weave pattern includes a second weave density, the second weave density being characterized by a second plurality of fibers of the second woven layer.

5. The substrate of claim 4 , wherein the second weave density is greater than the first weave density.

6. The substrate of claim 4 , wherein the third layer comprises a third plurality of fibers, the third plurality of fibers connecting at least one of the first plurality of fibers and the second plurality of fibers to form the substrate.

7. The substrate of claim 6 , wherein the third layer includes a surface density between about 75 grams per square meter and about 500 grams per square meter.

8. The substrate of claim 1 , wherein materials of the first and second woven layers each comprise polyester.

9. A substrate for emitting a volatile material, the substrate comprising:
a first woven layer having a first weave pattern that includes a first weave density;
a second woven layer having a second weave pattern that includes a second weave density; and
a third layer that is disposed between the first woven layer and the second woven layer,
wherein the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

10. The substrate of claim 9 , wherein the volatile material includes an active agent that is applied to at least one of the first woven layer, the second woven layer, and the third layer.

11. The substrate of claim 9 , wherein the first weave density is characterized by a first plurality of fibers of the first woven layer and the second weave density is characterized by a second plurality of fibers of the second woven layer.

12. The substrate of claim 11 , wherein the second weave density is greater than the first weave density.

13. The substrate of claim 11 , wherein the third layer comprises a third plurality of fibers, the third plurality of fibers connecting at least one of the first plurality of fibers and the second plurality of fibers to form the substrate.

14. A substrate for emitting a volatile material, the substrate comprising:
a first woven layer having a first weave pattern;
a second woven layer having a second weave pattern that is different than the first weave pattern; and
a third layer that is disposed between the first woven layer and the second woven layer,
wherein the volatile material includes an active agent that is applied to at least one of the first woven layer, the second woven layer, and the third layer, and
wherein the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

15. The substrate of claim 14 , wherein the first woven layer includes a first thickness and the second woven layer includes a second thickness that is different than the first thickness.

16. The substrate of claim 14 , wherein the first weave pattern is a first honeycomb weave pattern and the second weave pattern is a second honeycomb weave pattern.

17. The substrate of claim 14 , wherein the first weave pattern includes a first weave density, the first weave density being characterized by a first plurality of fibers of the first woven layer, and
wherein the second weave pattern includes a second weave density, the second weave density being characterized by a second plurality of fibers of the second woven layer.

18. The substrate of claim 17 , wherein the first weave density is different than the second weave density.

19. A substrate for emitting a volatile material, the substrate comprising:
a first woven layer having a first weave pattern that includes a first weave density;
a second woven layer having a second weave pattern that includes a second weave density; and
a third layer that is disposed between the first woven layer and the second woven layer,
wherein the volatile material includes an active agent that is applied to at least one of the first woven layer, the second woven layer, and the third layer, and
wherein the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

20. The substrate of claim 19 , wherein the first weave density is characterized by a first plurality of fibers of the first woven layer and the second weave density is characterized by a second plurality of fibers of the second woven layer, and
wherein the first weave density is different than the second weave density.

21. The substrate of claim 19 , wherein the period of time is at least seven months.
